Signs of BATTERY going dead

At night, If your gauge lights dim significantly when you step on the brakes, this might be a sign that your battery is about to die… Mine’s started dimming down quite a bit, like I turned down the brightness or something…

I noticed my bro’s eclipse did the same thing before his battery died, and mine did it for a few weeks before it gave out too…

I heard this is a common problem regardless of the condition of the battery, but for me, after I put in a new 3yr warranty battery from Autozone, it doesn’t dim at all anymore when I step on the brakes… :smiley:

Well after I switched my battery I noticed the starter spun a lot faster, but my lights still dim when I hit the brakes… I’m gonna proceed to change my grounds, if that doesn’t work, possibly it’s the voltage regulator?

hmm… interesting. maybe it only affects SOME models?

does it dim alot or just barely noticeable?..

And I forgot to mention, it ALSO dims when my car was idling too… then when I got going again, the lights brighten back to normal…

The alternator may be at fault if your lights go dim while the car is running.

I would also say if it still does it…then your ground is bad or your alternator is getting tired.

Later!

Which grounds should I check? and replace?

Cause when I tap my brakes, the lights dim, like a slight flutter to them. Kinda like when you have the stereo up really loud.

Just make sure that the ground on the battery makes a good connection and no corrision…it also could be as simple tightening the ground terminal.

When you disconnect the battery and leave it off for a while, it will corrode the metal. When I got my car back from getting the clutch installed my car had dimmed lights and would dim really bad when I pressed the brakes. I cleaned the battery terminals and the cable terminal brackets with a wire brush and the problem was solved.

I checked my terminals an they look like crap, I’m gonna pick up a tool to clean the terminals an the clamps.

you can also buy these red and green donut things that go around the terminals of the battery to help stop that white stuff from appearingi have those

I had that dimming problem and slow starter, replaced the battery, now the starter spins a lot faster, but the lights are still dimming when I brake… If I have the heater fan at full blast, I can also hear her slow down… I think it’s alternator related… mine is making a loud whining/whistling noise at 1K-1.5K RPM…

my battery light is on is that a sign of my battery going dead?

if the battery light comes on, it’s because the charging system is not recharging the battery… get your alternator checked asap!

Lights faintly pulse w/ sub?

Hey all!

Can you pick up on the comment about “kind of like when you have the stereo up really loud…”

I definitely have some barely noticeable dimming of headlights/dash lights when I crank up my new amp/sub.

Its been a long time since I’ve had anything but stock audio in my ride; do the lights indicate a normal draw on the electical system by the audio? Or is that sketchy; perhaps I need a new or stronger battery?

Any advice is much appreciated!

Peace.

Could be your alternator and/or battery…your best bet would be to install a AutoMeter voltage meter in a pillar pod…that way you can monitor it at all times and get a better idea of whats going on.

Thanks 92RSInteg!

Thanks… that’s a fun idea I hadn’t even thought of… and a good excuse to score a gauge for the car! :smiley:

Hell yeah dude…any excuse to upgrade is a good one to me.

Have fun man!

In a pinch I used Coca-Cola to remove some battery corrosion. Strangely effective. I got the red & green donut things and no problems since.

My lights dim somewhat when I hit the brake, but not during any other times. I think it is my alternator giving up the ghost…
